Definitions

  • the present invention relates to telecommunications networks, and more particularly relates to a method and an apparatus for controlling resource utilization for uplink communications in a telecommunications network.
  • FIG. 1 shows part of a telecommunications network 2.
  • the network 2 comprises a radio base station 4, which transmits signals to a mobile terminal 6 in downlink communications 8a, and receives signals transmitted by the mobile terminal 6 in uplink communications 8b.
  • the radio base station 4 further communicates with a core network 8.
  • the network 2 will in general comprise a plurality of radio base stations, with each radio base station transmitting to a plurality of mobile terminals.
  • the core network 8 in general comprises a multitude of different devices, which act to control the operation of the network 2, and to pass data, etc from one part of the network to another.
  • Both downlink communications 8a and uplink communications 8b are transmitted over a number of different channels, generally including data channels, for transmitting data, and control channels, for transmitting control signals. That is, the downlink communications 8a take place over at least a downlink data channel and a downlink control channel, and the uplink communications 8b take place over at least an uplink data channel and an uplink control channel.
  • UTRA UMTS terrestrial radio access
  • E-UTRA evolved UTRA
  • LTE long term evolution
  • the resources for transmitting the various channels are divided into so-called “resource blocks", which each define a portion of frequency and time. That is, the channels are time-division multiplexed (TDM) and frequency-division multiplexed (FDM).
  • TDM time-division multiplexed
  • FDM frequency-division multiplexed
  • CDM code-division multiplexing
  • the uplink data channel (e.g. PUSCH) is shared between a number of different users to enable an efficient use of resources.
  • a user In order to transmit data over a shared channel, a user must request and be granted an allocation of resources on that channel.
  • Such scheduling requests are sent over the uplink control channel, e.g. PUCCH, if resources for scheduling requests have been configured.
  • Scheduling requests are initiated by a buffer status report (BSR) trigger in the mobile terminal. This happens when some higher-layer mechanism determines that data needs to be delivered.
  • BSR buffer status report
  • the scheduling requests are transmitted within a defined periodic time slot, with the periodicity of scheduling requests being semi-statically configured by radio resource control (RRC) and ranging from 5 to 80 ms.
  • RRC radio resource control
  • a mobile terminal does not necessarily have scheduling-request resources (there is also an "off option) in which case it requests uplink grants by a transmission on the Random Access Channel.
  • acknowledgement messages are sent over the uplink control channel, e.g. PUCCH. If the data is correctly received, a positive acknowledgement (ACK) is sent; if the data is incorrectly received, a negative acknowledgement (NACK) is sent (or alternatively no acknowledgement message is sent).
  • ACK positive acknowledgement
  • NACK negative acknowledgement
  • MIMO multiple-input, multiple-output
  • more than one data stream may be sent to a single mobile terminal.
  • individual HARQ processes may be used for each data stream by sending different code words for each stream and acknowledging them (i.e. sending an ACK/NACK) individually.
  • the mobile terminal 6 therefore periodically sends channel quality indicators (CQIs) to the radio base station 4 over the uplink control channel, e.g. PUCCH.
  • CQIs channel quality indicators
  • the periodicity is configured, as with scheduling requests, by higher layers, and ranges from 2 to 256 ms (or alternatively may be completely "off').
  • the CQIs may include, for example, the signal strength; the delay spread; the path loss; the Doppler spread; the frequency error; the noise strength; the interference strength; and the signal to interference and noise ratio (SINR).
  • various messages are transmitted over the uplink control channel, including scheduling requests, ACK/NACKs, and CQIs.
  • a combination of TDM, FDM and CDM is used to spread the uplink control channel resources according to the various users' requirements.
  • Too aggressive an allocation of resources i.e. such that many mobile terminals transmit simultaneously on the same frequency resource
  • too cautious an allocation of resources i.e. with relatively few mobile terminals transmitting simultaneously on the same frequency resource
  • the embodiments of the present invention overcome the problems described above by actively monitoring the error rate of messages transmitted over the uplink control channel.
  • the measured error rate is then used to adapt the distribution of the messages transmitted over the uplink control channel.
  • the error rate is compared with one or more thresholds; if the threshold is exceeded, the distribution is adapted such that the error rate is decreased (for example by preferring time-division multiplexing over other multiplexing schemes).
  • the distribution is adapted such that the error rate is increased (i.e. such that resources are more fully utilized).
  • Different methods may be applied according to the type of messages transmitted over the uplink control channel: scheduling requests, channel quality indicators, or ACK/NACK messages.
  • a method of controlling resource utilization in a telecommunications network comprising a plurality of mobile terminals and at least one radio base station.
  • the mobile terminals are configured to transmit messages to the radio base station over an uplink control channel, and resources for the uplink control channel comprise a plurality of resource blocks, each resource block corresponding to a period of time and a frequency bandwidth.
  • the method comprises measuring an error rate of messages transmitted over the uplink control channel; and, on the basis of the measured error rate, adapting a distribution of messages over the plurality of resource blocks on the uplink control channel.
  • Figure 1 shows a telecommunications network
  • Figure 2 is a flowchart illustrating a method according to an embodiment of the present invention.
  • Figure 3 shows a radio base station according to an embodiment of the present invention.
  • radio base station may refer to a NodeB, as utilized in UMTS terrestrial radio access (UTRA), or an eNodeB, as used in evolved UMTS terrestrial radio access (E-UTRA), etc.
  • eNodeB as used in evolved UMTS terrestrial radio access
  • mobile terminal includes references to user equipment, as utilized in UTRA and E-UTRA.
  • the uplink control channel e.g. the PUCCH
  • the uplink control channel is monitored for errors.
  • steps are taken to adapt the distribution of messages received over the uplink control channel.
  • Such adaptation may include, for example, preferring time-division multiplexing over other multiplexing methods (frequency- and code-division multiplexing), such that fewer messages are received over the uplink control channel in a given transmission time interval (TTI).
  • TTI transmission time interval
  • Figure 2 is a flowchart of a method according to an embodiment of the present invention, for use in a telecommunications network as described with respect to Figure 1.
  • the method begins in step 20.
  • the radio base station 4 measures the error rate of messages received over the uplink control channel (e.g. the PUCCH).
  • An aggregate error rate for all messages may be measured, or individual error rates measured for each type of message.
  • the error rate for ACMMACK messages may be estimated through the detection of retransmissions on the radio link control layer (RLC).
  • ACK/NACK messages are transmitted, in one embodiment, as one symbol containing one or two bits, depending on the modulation scheme (binary phase shift keying or quadrature phase shift keying).
  • the symbol is detected by a threshold that is set at the detector via probability functions.
  • the threshold may be set so that the error case of NACK to ACK or a DTX to ACK (i.e. a transmitted NACK message or DTX being detected as an ACK message) has a lower occurrence probability than the other errors of ACK to NACK, ACK to DTX, DTX to NACK and NACK to DTX.
  • the latter errors mean only that a relatively fast (in some cases superfluous) retransmission of the packet takes place; the former errors imply a longer delay since data will be lost and the error case is detected by the slower RLC layer.
  • the error rate for CQI messages may be measured through the code applied to the CQI bits. That is, the bits of the CQI messages may be coded to make them more robust. In this case, the error rate of CQI messages may be measured by determining the difference between the detected CQI code word and the closest known CQI code word. For example, this may be achieved by counting the number of errors in the coded bits.
  • the error rate for scheduling requests may be estimated in a number of different ways. For example, the number of "false alarms" may be counted, i.e. the number of times a mobile terminal is allocated resources on the uplink data channel but does not use them. This may arise through corruption of the original scheduling request sent over the uplink control channel.
  • the error rate may be estimated by measuring the energy level on the scheduling request transmission. For example, the scheduling request may be determined as a scheduling request by comparing the energy transmitted over the scheduling request resources with a threshold. If the energy exceeds the threshold, the transmission is determined as a scheduling request from a particular mobile terminal. If the energy is close to the threshold (i.e. just over, or just under the threshold), it may be an indication that an error was likely in the transmission.
  • the mobile terminal comprises a counter which is adapted to count failed scheduling requests (i.e. transmitted scheduling requests that have not resulted in allocated resources on the uplink data channel). After x failed requests (where x is a certain number of failed requests), the mobile terminal may switch to random access in order to get a grant on the uplink data channel. The radio base station may then use a received random access message as an indication that at least x errors have occurred in scheduling requests transmitted by that mobile terminal.
  • the error rate may also be estimated by determining a delay estimate, looking at the transmitted data following the scheduling request.
  • the mobile terminal may continue to send scheduling requests until the radio base station grants resources on the uplink data channel. If the mobile terminal has to perform four scheduling request transmissions before it gets a grant, there will be a delay in the subsequent data transmission of three times the periodicity of the scheduling requests. If, however, the radio base station has correctly received the scheduling requests but decided not to grant resources for any other reason, it will know this and can disregard delays caused by such routes in order to determine an accurate scheduling request error rate.
  • the error rate is compared with a threshold. Where the error rate is an individual error rate for a particular type of message (e.g. CQI, scheduling request, ACK/NACK etc), the threshold is similarly an individual threshold for that particular type of message. Where the error rate is an aggregate of one or more of the individual error rates on the uplink control channel, the threshold is similarly an aggregate of those one or more individual thresholds.
  • step 26 if the error rate is below the threshold, no changes are made and the method ends at step 26 (except that it may be repeated in future). If the error rate exceeds the threshold, the method proceeds to step 28, where the distribution of messages over the uplink control channel is adapted. In one embodiment, the distribution is adapted such that fewer messages are sent to the radio base station 4 over the uplink control channel per transmission time interval (TTI) 1 i.e. time-division multiplexing is preferred to other multiplexing techniques.
  • TTI transmission time interval
  • the distribution of ACK/NACK messages is adapted by altering the scheduling of downlink communications. For example, when scheduling resources on the downlink data channel (e.g. the PDSCH) 1 larger bandwidths of frequency may be allocated to single mobile terminals, with consequently reduced numbers of mobile terminals being allocated to receive data in the same TTI. This in turn reduces the numbers of ACK/NACK messages received over the uplink control channel per TTI, acknowledging receipt (or not, as the case may be) of the data transmitted over the downlink data channel.
  • scheduling resources on the downlink data channel e.g. the PDSCH
  • 1 larger bandwidths of frequency may be allocated to single mobile terminals, with consequently reduced numbers of mobile terminals being allocated to receive data in the same TTI. This in turn reduces the numbers of ACK/NACK messages received over the uplink control channel per TTI, acknowledging receipt (or not, as the case may be) of the data transmitted over the downlink data channel.
  • MIMO communications are employed between the mobile terminal and the radio base station, with multiple individual data streams (code words) being transmitted simultaneously to the same mobile terminal, and individual
  • the distribution of ACK/NACK messages is adapted by altering the number of individual data streams. For example, the number of data streams may be reduced in order to reduce the number of ACK/NACK messages sent over the uplink control channel.
  • the distribution of CQI messages is adapted by altering the frequency with which CQI messages are sent by the mobile terminal, that is, by increasing or decreasing the channel state reporting period.
  • the channel state reporting period may be altered in the radio resource control layer, with the radio base station signalling the change to the mobile terminal.
  • the distribution of scheduling requests is adapted by altering the frequency with which scheduling requests are allowed to be sent by the mobile terminal.
  • the frequency may be altered in the radio resource control layer, with the radio base station signalling the change to the mobile terminal.
  • the distribution of messages may also be adapted if the error rate falls below the threshold. That is, if the error rate falls below the threshold, this may be an indication that resources are not being utilized efficiently.
  • the opposite of the steps described above may be performed to increase the number of messages received over the uplink control channel per TTI. For example, to increase the ACK/NACK error rate, downlink transmissions may be scheduled for an increased number of mobile terminals per TTI.
  • the threshold acts as a "target" error rate, i.e. one which has been determined as an ideal compromise between acceptable probability of errors and efficient utilization of resources.
  • the distribution of messages received over the uplink control channel is adapted by increasing or decreasing the amount of resources allocated to the uplink control channel itself. For example, by increasing the band of frequencies allocated to the uplink control channel, the messages can be spread out over a larger number of resource blocks, resulting in fewer messages sent per resource block.
  • FIG. 3 illustrates a radio base station 4 according to an embodiment of the present invention.
  • the base station 4 comprises an antenna 42, coupled to transmitting and receiving circuitry 44.
  • the Tx/Rx circuitry 44 is further coupled to processing circuitry 46.
  • the radio base station 4 comprises interface circuitry 48 for interfacing with the core network.
  • the base station 4 may comprise more than one antenna, and more than one Tx/Rx circuitry, for example in order to utilize MIMO communications as described above. All such variations are within the scope of the present invention as defined by the claims appended hereto.
  • the antenna 42 receives communications from one or more mobile terminals over different channels, including an uplink data channel and an uplink control channel, as described above.
  • the processing circuitry 46 measures an error rate of the received transmissions, for example as described with respect to step 22.
  • the processing circuitry 46 further compares the measured error rate with a threshold (as described with respect to step 24), and adjusts the distribution of messages sent over the uplink control channel according to any of the methods described with respect to step 28.
  • the processing circuitry may generate a message signalling an adjustment of the periodicity of CQI reporting, or the periodicity of resources over which scheduling requests may be sent by the mobile terminals.
  • the antenna 42 then transmits the generated message, for example, as an RRC message to the mobile terminals.
  • the processing circuitry 46 may adjust the distribution of resources allocated on the downlink data channel, such that they are more or less time-division multiplexed (thereby adjusting the distribution of ACK/NACK messages).
  • the measured error rate may be transmitted to the core network using interface circuitry 48.
  • the core network for example a radio network controller (RNC)
  • RNC radio network controller
  • the core network may then compare the error rate with a threshold as described with respect to step 24, and determine an appropriate adjustment to the distribution of messages transmitted over the uplink control channel. This adjustment may be signalled back to the radio base station 4, from where it is transmitted to the mobile terminals (in the case of CQI and/or scheduling request adjustment) or used to adapt the distribution of allocated resources on the downlink data channel.
  • the embodiments of the present invention therefore provide a method and a radio base station which actively monitor the error rate for messages transmitted over an uplink control channel between the radio base station and one or more mobile terminals.
  • the distribution of messages transmitted on the uplink control channel may then be adapted depending on the comparison of the error rate with one or more thresholds.
